This could also be achieved by raising the axles relative to the chassis while keeping them horizontal.

This is the point of dualies - there is always a roller in contact with the carpet, provided that they're mounted on a horizontal axis. Having multiple rollers in contact with the carpet at that angle will also introduce some additional friction as the rollers point in different directions.

The biggest issue is the one Wayne presented - wheels weren't meant to be loaded that direction. Omnis probably even more so - the whole point of omnis is that they don't exert a force parallel to the shaft. As a result, sound engineering would tend to reduce the sustainable force parallel to the shaft in favor of other requirements.
